Advantages Of BIM Over CAD
Building Information Modeling is touching heights with every passing day due to benefits like saving of overall cost and time during project cycle without affecting outputs. BIM booming in Middle Eastern countries is due to availability of latest Building Information Modeling software’s and also BIM solution providers.BIM technology results into reduced labor, time as well as cost, which result in BIM skilled workforce thus resulting into booming of BIM.
BIM – A common platform:
Building Information Modeling (BIM) technology provides a single integrated model with all the detailing, higher accuracy and also with reduced cost and time. BIM 3D models integrated models provide enriched data which are very useful for Contractors, Detailers, Architects, Structural Engineers and other personalities involved in the project, thus making BIM a common platform of communication.
BIM is now considered to be a vital tool in construction projects. Using BIM technology Architects, Structural Engineers, Project Managers coordinate with each other to create BIM 3D models. Created 3D Building Information Modeling (BIM) models are far better and more informative than 2D traditional drawing. 2D traditional drawing which are done in AutoCAD is slowly going towards dark and are replaced by 3D BIM smart models.
3D, 4D and 5D BIM models:
1. 3D BIM model:
3D BIM models are the smart models created by coordination of personalities of various domains which gives a clear view of how the actual model will look like after construction. Thus, it provides a clear and photorealistic view of residential houses, commercial buildings etc. before actual construction.
2. 4D BIM model:
Addition of time frame to 3D BIM models can be called as 4D BIM models. Thus, 4D BIM technology helps to create a proper time frame for the overall project title. This further helps to give estimation of time of completion of project which facilitate clients for further future planning etc.
3. 5D BIM model:
Including cost estimation feature to 4D BIM model results into 5D BIM Model. Hence 5D BIM model solves the cost estimation of the project. We can call 5D BIM model as cost analytical model because such model provides the overall cost estimation of the project.
Benefits of BIM:
1. 3D BIM model provides a common platform of communication for architects, contractors, structural engineers etc.
2. BIM models are enriched with ample data, construction schedules and reports which are used during construction phase.
3. BIM integrated models helps to save overall time and the cost of the project.
4. BIM provides material specifications, cost estimation and analysis as well as time of completion of project.
